目前我国很多工厂对于键槽对称度的检测多属被动测量,不能有效地、主动地控制产品质量,为此,我们研究开发了新型保证键槽对称度的装置,经实际使用证明,效果良好。一、结构原理及使用调整办法如图1所示,该保证装置由模拟被测轴线的心轴(模拟刀具) 和模拟基准轴线的定位V型块两部分组成,通过调整其相对位置就可保证对称度误差控制在允许范围内。其使用调整方法如下: 1.将模拟刀具——心轴安装在立式铣床主轴 At present, many factories in our country mostly measure the symmetry of the keyway passive measurement, which can not effectively and actively control the product quality. Therefore, we research and develop a new device to ensure the symmetry of the keyway, which is proved to be effective by actual use. First, the structure principle and the use of adjustment method shown in Figure 1, the assurance device by the simulated axis of the mandrel (simulation tool) and the analog reference axis positioning V-block composed of two parts, by adjusting its relative position can be guaranteed Symmetry error control within the allowable range. The use of adjustment method is as follows: 1. The analog cutter - mandrel mounted on the vertical milling spindle
